December, 2020: Sill Optics has extended their existing series of telecentric F-Theta lenses with a focal length of 48 mm to meet the ever increasing laser pulse power in micro processing.
The lenses can withstand even the highest fluences and are free from critical back reflections. The designs are optimised for scanners with 7 mm to 15 mm apertures and can be easily installed using an adapter ring.
Smallest spot diameters of 6 µm at 1064 nm wavelength, 3 µm at 532 nm and 2 µm at 355 nm can thus be achieved.
